Yes, that's cards. There are of course, two in this machine - nVidia GeForce 7800 GTXs operating in SLI configuration. As with the motherboard, nVidia has custom made the cards for Dell. Each is fitted with a large dual-slot heat pipe and fan cooler, similar to what nVidia has used on its new 512MB 7800 GTX cards. The PCBs on the Dell cards are full length with a metal bracket running down the spine. The only reason I can see for this is so that the cards can be secured in the bracket that also houses the internal fan with the advantage that there's less chance of anything coming out of place.
